fix: align identifier validation with spec constraints - #68
Use URL-safe ASCII identifier keys (letters, digits, dots, underscores, and hyphens) as the library baseline, with stricter rules wherever the specification requires them.
Reject dots in server keys.
Restrict component keys to ASCII.
Preserve the existing channel-key restriction.
Correct channel-address expression detection to include 0 and require nonempty names.
Add regression coverage for validation and parameter serialization.
Compatibility: dotted server keys and Unicode component keys now produce validation errors, while their values remain preserved in the model.
Summary by CodeRabbit
Bug Fixes
Corrected validation of channel-address expressions and server and component keys to better match their specification-defined formats.
Channel-key validation remains unchanged.
Tests
Added coverage for address-expression recognition and serialization, and for valid and invalid keys across supported AsyncAPI versions.
Use URL-safe ASCII identifier keys (letters, digits, dots, underscores,
and hyphens) as the library baseline, with stricter rules wherever the
specification requires them.
- Reject dots in server keys.
- Restrict component keys to ASCII.
- Preserve the existing channel-key restriction.
- Correct channel-address expression detection to include 0 and require
nonempty names.
- Add regression coverage for validation and parameter serialization.
Compatibility: dotted server keys and Unicode component keys now produce
validation errors, while their values remain preserved in the model.
The pull request updates channel-address expression recognition and key validation patterns. It adds tests for named expressions, YAML round-tripping, and channel, server, and component-message keys across AsyncAPI versions 2.6.0 and 3.0.0.
The expression pattern requires at least one character inside braces and permits 0. Tests cover named expressions, YAML round-tripping, and addresses that are not recognized.
Server and component key validation src/ByteBard.AsyncAPI/Validation/Rules/AsyncApiComponentsRules.cs, src/ByteBard.AsyncAPI/Validation/Rules/AsyncApiDocumentRules.cs, test/ByteBard.AsyncAPI.Tests/Validation/KeyRegexTests.cs
Component keys now use explicit ASCII letter and digit ranges. Server keys use a separate pattern that excludes periods. Tests cover channel, server, and component-message keys.
The identifier restrictions and expression changes have no established blocking regression. The newline-validation issue predates this change; the additional serializer test is a useful follow-up.

Explanation
The title "fix: align identifier validation with spec constraints" matches the main change. The PR tightens identifier validation: server keys reject dots, component keys are restricted to ASCII, and channel-address expression detection is corrected to include 0 and require nonempty names. The title is specific and concise. It omits the channel-address expression fix, but that is a secondary aspect.
Full details: Description check
Explanation
The description follows the repository's template loosely. It has a clear explanatory summary of the changes and a compatibility note, which covers the 'About the PR' content. It does not include the '### Changelog' section with Add/Remove entries, and it has no '### Related Issues' section with a 'Closes #' reference. Those sections are missing, so the description is only partly complete against the template.
Resolution
Add a '### Changelog' section with the appropriate entries, for example a 'Change:' or 'Fix:' item covering the server-key, component-key, and channel-address expression changes. Add a '### Related Issues' section. Link the issue this PR resolves with 'Closes #<issue-number>', or state that no issue applies.

Add a serializer-level test for an empty expression with parameters.
The negative test for orders/{} checks only IsChannelAddressExpression(). The serializer omits parameters: for this address only because of the predicate gate in AsyncApiChannel.cs. No test checks that output, so a change that writes parameters for this address would not fail the suite. The suggested test covers this case and uses the same APIs as the existing positive test.
Suggested test
address.IsChannelAddressExpression().Should().BeFalse();
}
++ [Test]+ public void EmptyExpression_OmitsParametersWhenSerialized()+ {+ var channel = new AsyncApiChannel { Address = "orders/{}" };+ channel.Parameters.Add("id", new AsyncApiParameter { Description = "Order identifier" });++ var yaml = channel.SerializeAsYaml(AsyncApiVersion.AsyncApi3_0);++ yaml.Should().NotContain("parameters:");+ }
}

Add a serializer-level test alongside IsChannelAddressExpression tests that
creates an AsyncApiChannel with address “orders/{}” and a parameter, serializes
it as AsyncAPI 3.0, and asserts the YAML omits “parameters:”. This verifies the
serialization behavior for an empty expression, not just the predicate result.

Use the strict \z end-of-string anchor for server key validation so keys
with a trailing newline cannot pass through the $ anchor.
Add regression cases for trailing LF, CRLF, and embedded newlines in
AsyncAPI 2.6.0 and 3.0.0. Escape carriage returns and newlines in
double-quoted YAML keys so the tests preserve these characters for
validation.
